Tuff one. i experiment often with combining different brands of kibble and usually get mixed results. What works today doesn't necessarily work tomorrow and vice versa. The current combo i'm feeding is homemade rice & chicken, blue buffalo wilderness high protein, topped off with a touch of royale canin wet stuff. The stools have been some of the best yet. I think the key is variety, it keeps the digestive track guessing. YMMV...
